Abstract
A photosensitive layer in a multilayer electrophotographic photoconductor includes a charge-generation layer including a charge-generating material having, as a major component, a titanyl phthalocyanine crystal which satisfies the conditions (A) and (B) below and a base resin, and a charge-transport layer including a charge-transporting material, the charge-generating material having, as a major component, the titanyl phthalocyanine crystal which has absorption at a wavelength of a charge-neutralizing light and which satisfies the conditions (A) and (B) or an X-form metal-free phthalocyanine crystal which has absorption at the wavelength of the charge-neutralizing light, and a binder resin. (A) In a Cu—Kα characteristic X-ray diffraction spectrum, one peak is present at a Bragg angle 2θ±0.2°=27.2°. (B) In a differential scanning calorimetry, one peak is present in a range of 270° C. to 400° C. except for peaks attributed to vaporization of adsorption water.
